I remember awhile ago Treyarch on their own forums wrote..This Essay of an excuse for the reason they wont have dedicated servers in CoD. So I don't believe this personally.
However, they might end up doing a bait and switch, using dedi servers for year and then when next gen starts they will just shut down Black Ops 2 Multi.
hmm...
If there is dedicated server on the console version.....Halo 4 might be in trouble for the multiplayer space this fall.
I can't stress this enough,
dedicated servers are most likely (I'm 98% sure) PC only. Activision has gone on record to state that dedicated servers will never come to consoles due to bandwidth costs etc. Methinks I should add that to the OP.
Of course, that could change, but I highly doubt it. Why spend on dedicated servers when they can save money and not do it? People will buy it either way.
Also, remember these are rumors, so take everything with a grain -- no a bag -- of salt. The source is from someone who claims to have spoken to an "associate producer" of Activision. So legitimacy is kinda questionable. Although some of the things mentioned do line-up with what we know so far (customizable loadouts that will let you choose perks over weapons, etc.).
